a lication filed April 16, 1915. Serial m. 21,627.

To all whom it may concern:

Be it known that I, AonLBnn'r D. KIGHT- 'LINGER, a citizen of the United States, residing at Washington, in the county of Washseveral brace members.

One of the objects in view is toprovide a corner joint member adapted to use with sectional corner uprights of ordinary unthreaded pipe sections, and having means for connecting the several horizontal and diagonal braces, as hereinafter more fully described.

The construction has in view to provide a derrick which can be built ofsections of commercial pipe having socketed engagement in cornerjoint members, and also brace sections of pipe, or flat bars, having bracing connection with the same members by lateral flanges or wings thereof, the terminal top and bottom corner members also tion of used between the top and bottom members.

having horizontal plate portions for attachment to a top structure and a supporting base respectively.

Referring to the drawings,-

Fig. 6 is a detail view in sectional elevation of one of the corner base members. 1

Fig. 7 is a diagrammatic view in eleyation of a complete derrick embodying'the invention. I v The derrick as a whole comprises corner base joint members 2, corner top JOHHHHGIH- bers 3, and intervening corner ointmembers 4, preferably otcast metal. Each of said members is provided with cylindrical sockets 5 for theinsertion of the ends of pipe sections 6 which abut against shoulders 7 of the joint members and have a bearing in side elevation of I support thereby. The intervening joint members 4; are provided with double shoulders 7 as shown, the same being provided by reducing the diameter of the pipe receiving opening whereby to provide the ofi'-set shoulder bearing, as readily seen.

. Each corner joint or connecting member, 2, 3 and 4, is provided with two pairs of laterally extending wings or checks 8, 8, spaced apart and adapted to receive between them the flattened terminal of the brace member, one pair being arranged in a direction at right angles to a similar pair, extending. vertglcally and laterally from the corner mem- 8 merge'into a top plate 9 having bolt holes 10 for attachment with the top or coping 11 ofthe derrick, the base members 3 having a similar plate 12 provided with similar bolt holes for attachment to a supporting base or platform. Intermediate joint members 1' are proyidedat oneend with a cross web 8 connecting the wings 8 and forming a bear:

The terminals of the braces 13 lie against the outer faces of the cheeks, and their inner'endsare cut ofi'angul-arly to provide a similar bracing connection against the face of the several members, the uppermost terminals of the upper set and the lowermost terminals of the lmwer set of diagonal braces, however, being inserted between the cheeks of the upper joint members 2, and lower joint members 3 respectively, and against similar vertical faces.

Bythis arrangement, the several brace members are -fixedly connected with the ,7 joint members and rigidly attached thereto,
